WARPING-MACHINE.

Specification of Letters Patent.

Patented llllar. 30, 1915.

Application filed August 13, 1912. Serial No. 714,841.

To all whom it may concern:

Be it known that I, EUGENE P. SEARING, citizen of the United States,residing at Paterson, in the county of Passaic and State of New Jersey,have invented certain new and useful Improvements in Warping-Machines,of which the following is a specification.

This invention relates to warping inachines and particularly to themeans for driving the reel on which in such a machine the warps arelaid. As heretofore constructed this means included a frictionwheel orband on the reel and a suitably driven friction-wheel which was shiftedinto contact with the first wheel to drive the same (and hence the reel)and out of contact therewith when the rotation of the reel was to stop.Backward rotation of the wheel, the necessity for which frequentlyarises in the warping operation, was required to be performed by hand bya pull exerted by the attendant on the warps after the reel had beenbrought to a stop-an operation which was both tedious and time-wastingand which involved more or less strain on the warps and occasionally thebreaking thereof. In accordance with the present invention the means fordriving the reel is so constructed that the attendant can cause it torotate the reel in either direction, as well as stand idle or neutralwith respect thereto so that the reel will remain stationary, and this,moreover, in a way involving his perfect control of the reel as thewinding or unwinding proceeds. Further, by the present invention thecharacter of the drive is such that the power is transmitted to the reelunder a condition more positive than heretofore when the reel is beingrotated forward and hence against the resistance exerted by the warp.

The invention will be found fully illustrated in the accompanyingdrawings, wherein,

Figure 1 is a side elevation of a warping machine constructed inaccordance with the present invention; Fig. 2 is a front elevationthereof, partly in section; and, Fig. 3 is a horizontal sectional viewin a plane just above the wheel d.

In the frame a; is journaled in the usual manner the reel Z) to which isattached the usual. driven wheel a. Adapted to peripherally engage thewheel a is the driving wheel (Z which, according to the usualconstruction, forms substantially one member with the pulleys 6 aroundeither of which extends the driving belt itself driven by the suitablyrotated pulley f around which it also extends. In the usual constructionwheel (Z is shifted into peripheral contact with wheel 0 while rotatingso as to drive the reel in the direction for winding the warps thereonand out of such contact when the reel is to be brought to a stop. In thepresent con struction, however, I provide an endless belt 9 whichextends loosely around both of the wheels 0 and cl and through it drivethe reel forward (in the direction for winding the warps thereon) byshifting wheel d into driving contact therewith, driving the reelbackward (in the direction for unwinding the warps) by shifting saidwheel (Z into driving contact with wheel 0, and bringing the reel to astop by moving or shifting the wheel d to a neutral position relativelyto wheel 0 and the belt. It will be obvious that by this arrangement Iobtain a far better tractive effect of wheel cl to drive the reelforward (the condition under which it opposes greatest resistance) thanformerly, due to the extended contact which it now has with the elementdriven thereby (belt 9), besides providing for also driving the reelbackward from wheel d. The peripheral surfaces of wheels 0 and at beingpreferably flat so as to insure a good grip of the one on the other itis preferable to guide the belt 9 by means of a grooved idler pulley itaround which the belt also extends, the same being journaled in abracket 2'.

I preferably provide the following mechanism for controlling theposition of wheel (Z. The arbor j carrying said wheel and pulleys e isjournaled in an arm is pivoted to the frame and having the depending lugZ. To this lug is pivotally attached the rear end of a lever on which isfulcrumed between its ends on a vertically adjustable stud a secured inthe frame and from the forward end of which depends the link 0, pivotedthereto. Link 0 is shifted up or down to bring the wheel (Z to any ofthe three positions mentioned as follows: In the frame is fulcrumed atreadle lever 29 pivotally connected to the link as a lever of thesecond class, its fulcrum being the stud 9, it is connected with thelink between the ends thereof. In the frame is also fulcrumed thetreadle lever 1' pivotally connected with the link as a lever of thefirst class, its fulcrum being the stud s; it is connected with thelower end of the link. It will be obvious that when treadle r of lever7' is depressed the wheel (Z will be shifted downwardly against belt 9so as to drive the reel forward, and that when the treadle p of lever 79is depressed the wheel (Z will be shifted upwardly against wheel 0 so asto drive the reel backward.

In the arrangement shown there is a condition of balance in the systemof parts cl and e and j to r tending to preserve them in any position towhich they may be moved. But it is preferable to provide means forreturning the parts to the position shown in Fig. 1, that is, where (Zis neutral to or out of contact with both 9 and e, immediately downwardpressure on treadle r is removed, the same consisting in the adaptationshown of an extensible elastic and flexible link t connecting lever rwith the frame and opposing downward movement of said lever from thesaid position. The treadles p and r" are arranged so that the former isslightly further inward than the latter and (in the neutral position ofd, Fig. 1) slightly higher than the same, an arrangement found bestsuited for accomplishing in a convenient, quick and effective way thevarious movements of the system, and obviously allowing quick stoppingand the reversing of the reel. by changing the pressure from one to theother of the leversJ Having thus fully described my invention, what Iclaim and desire'to secure by Letters Patent is:

A warping machine including, with the frame and the reel journaledtherein and having a wheel forming a fixed part thereof, an endless beltloosely embracing the wheel, a driving wheel arranged between the beltand the first wheel and shiftable back and forth out of driving contactwith one into driving contact with the other of them, and means forshifting the driving wheel back and forth including a pair of leversfulcrumed in the frame and each having a treadlc at one end, and means,common to both levers, for transmitting shifting motion from the leversto said driving wheel, one of said levers being a lever of the secondclass and having the motion transmitting means connected therewithbetween its ends and the other lever being a lever of the first classand having said motion transmitting means connected therewith at itsother end, substantially as described. v

In testimony whereof I affix my signature in presence of two witnesses.
